Measuring my TRT dose

I didn't ask nearly enough questions when I started TRT. I assumed I knew how to translate my prescribed dose into an amount of the liquid in a syringe.

I was wrong.

Syringes come in different capacities. They are typically measures in cubic centimeters (cc), milliliters (mL) or units.

Luckily, cubic centimeters and milliliters are equivalent. They are the same physical unit of measure.

I am prescribed testosterone cypionate 1mL weekly. I divide this 1mL weekly dose into two 0.5mL doses injected twice weekly on Tuesday and Friday mornings.

Units are a measure where concentration is varied based on the vitamin, hormone, or vaccine in question. A standards board sets the concentration found in each unit for each vitamin, hormone, or vaccine.

The concentration defined for a unit of Vitamin C is different than the concentration for a unit of human chorionic gonadotropin (HCG).

As a physical unit of measure, 100 units is equivalent to 1mL or 1cc.

I am prescribed 25 units human chorionic gonadotropin (HCG) weekly. I inject this prescribed dose once a week on Friday.

To make the measurement of the doses easy, I brought syringes with complimentary capacities.

For injecting the testosterone cypionate, I found syringes with 1mL capacity. This makes measuring 0.5mL doses easy. I fill the syringe halfway to 0.5 using the scale printed on the side.

For injecting the human chorionic gonadotropin (HCG), I found syringes with 50 units capacity. I fill the syringe halfway to 25 units using the scale printed on the side.
